Apply patch from Munteanu Veaceslav to fix SimpleViewer XML file syntax, to be compatible with current version available.
Fix a litle bug if user press cancel on first run dialog. No need a warning message box in this case.

It still a problem to open generated target index.html : Flash component is not visible on the page.
If simpleviewer.swf is open instead, all work fine as espected. I suspect something wrong in index.html page generated by the plugin.
